These exams are not deferrable; however, they are required only B-G-1/86.200 when the B-L-2 visual exam of the internal surfaces of a pump are performed. During the 2nd period, the B-L-2 visual exam was performed on RC Pump B and the Item 86.180 pump studs, Item B6.190 flange surface, and Item B6.170 nuts were examined. Only one pump Is required to be examined per B-L-2 requirements, thus, B-G-1 requirements were satisfied.

Exams are deferrable until the end of the 3Mu Interval. Item B-N-2/ B13.30 numbers are combined because a VT-1 Is performed on all attachment welds.
B-N-2/B1 3.40 NA NA NA NA Exams are deferrable until the end of the 3'" interval; therefore, N-532-1 percentages do not apply. The accessible surfaces of the Top Guide, Core Plate and Hold-Down Bolts, Shroud, Shroud Support Ledge, Shroud Tie Rods, Control Rod Guide Tubes, Control Rod Housing & Stub Tubes, and Fuel Support Pieces are examined during the 10-year interval.

C-H/C7.60 Therefore, pressure testing of virtually all Class 2 piping and C-H/C7.80 components Is performed In conjunction with system operating or surveillance procedures. Piping and components that are not pressurized In conjunction with any system operating procedure or system surveillance procedure require a N-498-1 pressure test once per interval. There are only two Class 2 tests that are not performed using either system or surveillance procedures. These two tests are performed once each Interval and the ASME Xl Code allow deferral until the end of the Interval; therefore, reporting percentage completion for these pressure tests Is not approp ate.
